DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 239,362, dated March29, 1881.

Application filed December 28, 1880.

1'0 all whom it may concern:

Be it known that I, BENJAMIN F. BLYE, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Door- Hangers, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to the class of doorhangers which suspend thedoor from a bar riding on the axle of independent rollers mounted onstationary tracks above the door.

The invention consists in a novel, simple, and comparatively inexpensiveconstruction of a door-suspending frame, possessing superior stabilityand great facility of adjustment to the width of the door to which it isto be applied; and it also consists in a peculiar construction andcombination of devices for supporting and guiding thedoor-suspendingframe when in operation, all as hereinafter more fullydescribed.

The accompanying drawings fully illustrate the invention.

Figure 1 is a front view of my improved door-hanger; Fig. 2, an enlargedtransverse section on line as m, and Fig. 3 an enlarged transversesection on line 3 y.

Similar letters of reference indicate corresponding parts.

D denotes the door, designed to be suspended. In the side edges of saiddoor is countersunk and rigidly secured a strap, 112, having offsets orlugs to, with a hole through which the suspension-rod a passes, said rodbeing provided at its lower extremity with a head, h, which engages thebottom of the lower lug, u, and thus supports the door. Theupperextremity of the suspension rod or is screwthreaded and passes through acorrespondingly female-threaded eye, d, on the end of the carrier-bar B,and thus affords a simple and effective means for adjusting theelevation of the door.

The carrier-bar B, I form of metal and of two sections, ,1) b spliced byoverlapping each other, and braced by flanges on one section embracingthe edges of the other section, as shown at s, and clamped by bolts 0 apassing through a slot or slots, 6, in one or both sections 1) b, saiddescribed connection afiording (Model) a convenient and effective meansfor ad justing the hanger to various widths of doors without impairingthe stability of the hanger. Each of said sections has its bottom edgeformed with an elongated and straight recess terminating with abruptotl'sets ff, which serve as stops for limiting the movement of the barB, said bar riding with the aforesaid recess on the axle o of therollers rm, and the collision of the offsets ff with the axles 0determining the movement of the bar, as aforesaid. The rollers aresufficiently apart to prevent frictional contact of same with the bar B.By means of a hub or boss, n, on the inner side of the respectiverollers abutting against the sides of the bar B, the latter is steadiedand guided. Heretofore both rollers r r have been either flanged andmade to serve as guiderollers, or were made smooth-faced and traveled ona plain track-rail, as shown at It, and were guided either by additionalrollers or stays connected to the suspension-rods between thetrack-rails. The first-mentioned arrangement, however, requires bothtrack-rails to be perfectly true and parallel to each other, inasmuch asthe bending or deviation, of either rail tends to bind the rollers andimpede their movement. The other arrangement increases the cost ofmanufacture and adds to the device frictional bearings which aredifficult of access for lubricating, and consequently subject the sameto wear and abrasion, which soon render the door-hanger defective orinoperative. To obviate these defects, I make one roller, r, with anarrow grooved tread and mount it on a guide-rail, R, formed of astraight bar or piece of band-iron, i, secured edgewise to a woodenrail, R, as best seen in Fig. 2 of the drawings. The described combinedcarrying and guide roller, in conjunction with the metal guide-rail,dispenses with the usual extra rollers and other devices heretoforeapplied to the door-hanger for guiding the door in its movement, and isnearly or quite free from friction, wear, and noise. The other roller,r, is smoothfaced, and travels on a plain smooth trackrail, R. Saidroller being thus relieved of all obstructions in its movement, andguided by the roller r, on the opposite side of the hanger, it becomesimmaterial whether the rail R is perfectly true and parallel with theguide-rail R, thereby saving to a great extent time, labor, and expensein applying the device to a doorway.

I do not claim, broadly, the combination of two rollers connected by arigid axle and a carrier-bar traveling on said axle, as I am aware thesame is not new; but

What I do claim as a specific improvement in that class of devicesis- 1. The within-described door-suspending frame, consisting of the barB, composed of sections 12 I), having the splice s, with slot 0 andbolts 0, and provided with the stops f f, and with the female-threadedeye, 61, and the suspension-rods c a, having their upper cxtremityscrew-threaded, and their lower extremity provided with the head h, allconstructed and adapted to be applied to a door, substantially in themanner described and shown.

2. The improved means for carrying and guiding a suspended door,consisting in the combination, with the carrier-bar B, of the plaintrack-rail R, guide-rail B, provided with the bar i, the plain facedroller 1", and grooved roller 1, connected by a rigid axle and mounted,respectively, on the rail R and bar 1', substantially in the mannerdescribed and shown.

In testimony whereof I have hereunto signed my name and aifixed my sealin the presence of two attesting witnesses, at Syracuse, in the countyof Onondaga, in the State of New York, this 21st day of December, 1880.
